Add support for micronaut 4

[bjor-joh]

There is a todo to upgrade to micronaut 4.x. Any concrete plans for this?

I tried using the existing version with micronaut 4 a while back but it didn't work.

Category (place an x in each of the [ ])

• [ ] bolt (Bolt for Java)
• [ x ] bolt-micronaut (Bolt for Java - optional modules)
• [ ] slack-api-client (Slack API Clients)
• [ ] slack-api-model (Slack API Data Models)
• [ ] slack-api-*-kotlin-extension (Kotlin Extensions for Slack API Clients)
• [ ] slack-app-backend (The primitive layer of Bolt for Java)

Hi @bjor-joh, thanks for writing in. We will update the module to support Micronaut 4 in the future, but I cannot tell when the change will be released. The module is quite simple and it has only two source files. If you're in a hurry to use Micronaut 4, please fork the implementation and adjust it to work with v4.

@bjor-joh I am definitely late to the party here but just came across this issue now. You should be able to get things working using Micronaut's @Import (which they say only works in java but seems fine in kotlin for me, possibly they mean the whole jvm or documentation is just out of date)

example:

import io.micronaut.context.annotation.Import
import io.micronaut.runtime.Micronaut

// checks these packages for JSR-330 annotated classes to make beans
// can also just be specific classes, which i did in my own use case
@Import(packages = ["com.slack.api.bolt.micronaut"])
object Application {
  @JvmStatic
  fun main(args: Array<String>) {
    Micronaut.build()
      .packages("com.github.example")
      // ... other setup you might do 
      .mainClass(Application.javaClass)
      .start()
  }
}
